docs: remove empty Why OpenCLI section and clean up Highlights (#1008)

- Remove the empty "Why OpenCLI" heading
- Rename "CLI All Electron" to "Desktop App Control" for clarity
- Remove "Anti-detection built-in" (exposes implementation details)
- Remove "Broad coverage" (duplicates intro and Built-in Commands table)
- Merge "Self-healing setup" and "Dynamic Loader" out (minor features)
- Rename "External CLI Hub" to "CLI Hub" for brevity

 It also works as a **CLI hub** for local tools such as `gh`, `docker`, and other binaries you register yourself, plus **desktop app adapters** for Electron apps like Cursor, Codex, Antigravity, ChatGPT, and Notion.

 ## Highlights
 
-- **CLI All Electron** — CLI-ify apps like Antigravity Ultra! Now AI can control itself natively.
-- **Browser Automation** — `browser` gives AI agents direct browser control: click, type, extract, screenshot — any interaction, fully scriptable.
-- **Website → CLI** — Turn any website into a deterministic CLI: 87+ pre-built adapters, or crystallize your own with `opencli record`.
+- **Desktop App Control** — Drive Electron apps (Cursor, Codex, ChatGPT, Notion, etc.) directly from the terminal via CDP.
+- **Browser Automation** — `browser` gives AI agents direct browser control: click, type, extract, screenshot — fully scriptable.
+- **Website → CLI** — Turn any website into a deterministic CLI: 87+ pre-built adapters, or generate your own with `opencli generate`.
 - **Account-safe** — Reuses Chrome/Chromium logged-in state; your credentials never leave the browser.
-- **Anti-detection built-in** — Patches `navigator.webdriver`, stubs `window.chrome`, fakes plugin lists, cleans ChromeDriver/Playwright globals, and strips CDP frames from Error stack traces. Extensive anti-fingerprinting and risk-control evasion measures baked in at every layer.
 - **AI Agent ready** — `explore` discovers APIs, `synthesize` generates adapters, `cascade` finds auth strategies, `browser` controls the browser directly.
-- **External CLI Hub** — Discover, auto-install, and passthrough commands to any external CLI (gh, obsidian, docker, etc). Zero setup.
-- **Self-healing setup** — `opencli doctor` diagnoses and auto-starts the daemon, extension, and live browser connectivity.
-- **Dynamic Loader** — Simply drop `.js` adapters into the `clis/` folder for auto-registration.
+- **CLI Hub** — Discover, auto-install, and passthrough commands to any external CLI (gh, docker, obsidian, etc).
 - **Zero LLM cost** — No tokens consumed at runtime. Run 10,000 times and pay nothing.
 - **Deterministic** — Same command, same output schema, every time. Pipeable, scriptable, CI-friendly.
-- **Broad coverage** — 87+ sites across global and Chinese platforms (Bilibili, Zhihu, Xiaohongshu, Reddit, HackerNews, and more), plus desktop Electron apps via CDP.
